Description

Technical Field

[0001] This invention relates to the field of welding, and more particularly to a large-scale tubular column welding and forming system. Background Technology

[0002] Steel pipe columns are often used in building construction. However, the shape of the steel pipe columns used varies depending on the location where they need to be installed. Therefore, selective welding of the steel pipe columns is necessary before use.

[0003] Chinese utility model patent CN213560842U discloses an auxiliary device for welding steel pipe columns in construction, including a support base. The device is characterized by: a support plate fixedly installed in the middle of the support base; a clamping device installed in the middle of the support plate; two support arms rotatably installed on both sides of the support plate at its front end; a locking device fixedly installed on the outer wall of each support arm; and a linkage device installed inside the support base to coordinate with the two support arms. This utility model achieves multi-angle welding through the use of the support plate and support arms, and the clamping device and the two support arms allow the welded steel pipe column to be flipped, thus facilitating welding.

[0004] The aforementioned utility model patent can achieve the purpose of welding, but it cannot clamp and fix pipe columns of different diameters during use. It can only limit and fix pipe columns of a single diameter, which limits its application range. It cannot limit and fix multiple types of pipe columns and cannot provide good pipe column limiting. Summary of the Invention

[0005] To address the technical problems of not being able to clamp and fix pipe columns of different diameters during use, being able to limit and fix only pipe columns of a single diameter, having a limited range of applications, not being able to limit and fix multiple types of pipe columns, and not being able to provide good pipe column limiting technology, this invention provides a large pipe column welding and forming system.

[0006] The present invention is achieved by the following technical solution: a large-scale pipe column welding and forming system, comprising a main body of the pipe column welding and forming system, the main body of the pipe column welding and forming system comprising a pipe column limiting mechanism and a welding mechanism, the pipe column limiting mechanism comprising an outer limiting clamping mechanism and an inner limiting clamping mechanism;

[0007] The external limit clamping mechanism includes:

[0008] The outer contour is circumferential. The inner side of the outer contour is provided with a locking tooth. The inner contour meshes with the inner contour. The outer contour and the inner contour mesh together. The inner side of the inner contour is fixedly connected with a pressure block. The outer limit clamping mechanism also includes a limit ring. A movable block is installed on the outer surface of the limit ring. The movable block passes through the surface of the limit ring and is movably connected to an outer clamping block.

[0009] The inner limit clamping mechanism includes:

[0010] The mounting ring supports the inner limiting clamping mechanism. The mounting ring is circular in shape, and a bushing is fitted on the outer surface of the mounting ring. An inner clamping block is connected above the bushing, and a push block is connected below the bushing. The inner clamping block and the push block are connected through the bushing. The inner limiting clamping mechanism also includes an outer turntable. The outer surface of the outer turntable is provided with pressing protrusions. The outer turntable is circular in shape, and the inner turntable is meshed with the inner turntable through gears on the inner side of the outer turntable.

[0011] The tube column to be welded is passed through the tube column limiting mechanism. The hollow tube column passes through the tube column limiting mechanism, and the tube column wall is stuck in the gap between the outer limiting clamping mechanism and the inner limiting clamping mechanism as shown in the figure. After the tube column passes through the tube column limiting mechanism, the worker rotates the handle. The rotating handle drives the connecting frame to rotate, and the connecting rods connected to both ends of the connecting frame are driven synchronously. At the same time, the through rod connected to the inner side of the connecting frame keeps rotating synchronously.

[0012] By deflecting the connecting rod, the connecting rod synchronously drives the outer contour connected to it to rotate. The outer contour drives the inner contour on its inner side to rotate synchronously through the meshing teeth. The inner contour then drives the pressure block connected to its inner side to deflect synchronously. As the pressure block deflects, it then presses the movable block. The movable block is then pressed down, and the outer clamping block connected to the movable block is then driven to press down synchronously. The outer clamping block is then pushed out to fix and clamp the outer wall of the tube column.

[0013] Simultaneously, the through rod connected to the inner side of the connecting frame rotates synchronously, thereby driving the inner turntable connected to it to rotate synchronously. The inner turntable then drives the outer turntable to rotate synchronously through meshing gears. The pressing protrusion connected to the outer side of the outer turntable is also driven synchronously, and the pressing protrusion then squeezes the push block, which is then pushed. The push block then drives the inner clamping block connected to it to be pushed synchronously, and the inner clamping block clamps the inner wall of the tubing. By clamping the tubing inside and outside through the outer and inner clamping blocks, the tubing is fixed. Through the clamping and limiting between the outer and inner limiting clamping mechanisms, tubing of different diameters can be clamped and limited.

[0014] As a further improvement to the above scheme, the inner limiting clamping mechanism is set inside the outer limiting clamping mechanism, and a clamping cavity is formed between the inner limiting clamping mechanism and the outer limiting clamping mechanism, with the hollow tube column passing through the clamping cavity.

[0015] As a further improvement to the above solution, the string limiting mechanism includes:

[0016] The connecting rod passes through the mounting ring on each set of external limit clamping mechanisms and is movably connected to the mounting ring; the connecting frame is connected to the end of the connecting rod and is perpendicular to the connecting rod; the rotating handle is installed on the outside of the connecting frame, and a through rod is connected to the inside of the rotating handle and perpendicular to the connecting frame.

[0017] Mounting base; support beam, the support beam passing through and connecting the outer limit clamping mechanism and the mounting base.

[0018] As a further improvement to the above scheme, the through rod passes through the inner limiting clamping mechanism of each group, and the through rod is connected to the inner turntable of each group. In the moving state, the pressure block overlaps with the movable block, and in the moving state, the pressing protrusion overlaps with the push block.

[0019] As a further improvement to the above solution, the welding mechanism includes:

[0020] A support platform supports the main body of the welding mechanism; a support frame is fixedly connected at its bottom to the top of the support platform, and the top of the support frame supports a column limiting mechanism connected to the bottom of the mounting base.

[0021] A movable rod is connected to a support frame; a movable block is fitted onto the outer surface of the movable rod; and a movable platform is connected to the movable block, which moves on the outer surface of the movable rod.

[0022] As a further improvement to the above solution, the welding mechanism also includes: a mounting plate, which is fixedly connected to the top of the moving platform; a rotating shaft, which is located at the top of the mounting plate, and a welding shaft is connected to the outside of the rotating shaft. The welding shaft and the mounting plate are movably connected through the rotating shaft. A receiving shaft is connected to the outside of the welding shaft, and a ball head block is engaged with the inside of the receiving shaft. A welding head is connected to the outside of the ball head block.

[0023] The welding shaft can be deflected on the mounting plate by rotating the shaft center, adjusting the tilt angle of the welding shaft. The ball head block can be deflected inside the receiving shaft, and the angle position of the ball head block can be adjusted at all angles, thereby driving the welding head to adjust the angle and realize the welding of the clamped pipe column.

[0024] As a further improvement to the above solution, the welding mechanism also includes:

[0025] The drive motor is mounted above the support platform; the motor shaft is connected to the drive motor, and a telescopic rod is connected to the outside of the motor shaft. A receiving block is connected to the top of the telescopic rod, and the receiving block is connected to the bottom of the moving platform.

[0026] After the tubing column is clamped and limited by the tubing column limiting mechanism, the welding mechanism starts working. The drive motor drives the telescopic rod to move through the motor shaft, controlling the extension and retraction of the telescopic rod. The receiving block connected to the top of the telescopic rod moves synchronously, driving the moving platform connected above it to move synchronously. The moving platform then drives the moving block to move synchronously on the moving rod. The position of the moving platform is adjusted, and the mounting plate connected above the moving platform keeps moving synchronously, thereby driving the welding head to adjust its lateral position.

[0027] As a further improvement to the above solution, a groove is provided on the receiving shaft, and a ball head block is inserted into the groove on the receiving shaft. The ball head block deflects within the groove on the receiving shaft to adjust the angle. The tubular column limiting mechanism is installed above the welding mechanism, and the welding head is located below the welding mechanism.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. The present invention uses an outer clamping block and an inner clamping block to clamp the tubing from the inside and outside, thereby fixing the tubing. Through the clamping and limiting between the outer limiting clamping mechanism and the inner limiting clamping mechanism, tubing of different diameters can be clamped and limited.

[0030] 2. In this invention, the deflection of the connecting rod synchronously drives the outer contour connected to it to rotate. The outer contour drives the inner contour on its inner side to rotate synchronously through the meshing teeth. The inner contour then drives the pressure block connected to its inner side to deflect synchronously. As the pressure block deflects, it then presses the movable block. The movable block is then pressed down, and the outer clamping block connected to the movable block is then driven to press down synchronously. The outer clamping block is then pushed out to fix and clamp the outer wall of the tube column.

[0031] 3. In this invention, the through rod connected to the inner side of the connecting frame keeps rotating synchronously. The through rod drives the inner turntable connected to it to rotate synchronously. The inner turntable drives the outer turntable to rotate synchronously through meshing gears. The pressing protrusion connected to the outer side of the outer turntable is driven synchronously. The pressing protrusion then squeezes the push block, which is pushed. The push block then drives the inner clamping block connected to it to be pushed synchronously. The inner clamping block clamps the inner wall of the tube column.

[0032] 4. The welding shaft of this invention can be deflected on the mounting plate by rotating the shaft center, and the tilt angle of the welding shaft can be adjusted. The ball head block can be deflected inside the receiving shaft, and the angle position of the ball head block can be adjusted at all angles, thereby driving the welding head to adjust the angle and realize the welding of the clamped pipe column.

[0042] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0043] Example 1:

[0044] Please combine Figures 1-6This embodiment proposes a large-scale tubular column welding and forming system, including a tubular column welding and forming system body 1. The tubular column welding and forming system body 1 consists of a tubular column limiting mechanism 2 and a welding mechanism 3. The tubular column limiting mechanism 2 includes an outer limiting clamping mechanism 21 and an inner limiting clamping mechanism 22. The inner limiting clamping mechanism 22 is disposed inside the outer limiting clamping mechanism 21, and a clamping cavity is formed between the inner limiting clamping mechanism 22 and the outer limiting clamping mechanism 21. The hollow tubular column passes through the clamping cavity.

[0045] The outer limiting clamping mechanism 21 includes:

[0046] The outer contour 211 is circumferential. The inner side of the outer contour 211 is provided with a locking tooth. The inner contour 212 is engaged with the inner side of the outer contour 211. The outer contour 211 and the inner contour 212 are engaged together. The inner side of the inner contour 212 is fixedly connected with a pressure block 213. The outer limiting clamping mechanism 21 also includes a limiting ring 214. A movable block 215 is installed on the outer surface of the limiting ring 214. The movable block 215 passes through the surface of the limiting ring 214 and is movably connected to an outer clamping block 216.

[0047] The inner limit clamping mechanism 22 includes:

[0048] Mounting ring 221 supports inner limiting clamping mechanism 22. Mounting ring 221 is generally circular. Bushing 222 is sleeved on the outer surface of mounting ring 221. Inner clamping block 223 is connected above bushing 222. Push block 224 is connected below bushing 222. Inner clamping block 223 and push block 224 are connected through bushing 222. Inner limiting clamping mechanism 22 also includes outer turntable 225. Pressing protrusion 226 is provided on the outer surface of outer turntable 225. Outer turntable 225 is generally circular. Inner turntable 227 is meshed with the inner side of outer turntable 225 through gears.

[0049] The tubular column limiting mechanism 2 includes:

[0050] A connecting rod 23 passes through the mounting ring 221 on each set of outer limiting clamping mechanisms 21 and is movably connected to the mounting ring 221; a connecting frame 24 is connected to the end of the connecting rod 23 and is perpendicular to the connecting rod 23; a rotating handle 25 is installed on the outside of the connecting frame 24, and a through rod 26 is connected to the inside of the rotating handle 25 and perpendicular to the connecting frame 24;

[0051] Mounting base 27; support beam 28, the support beam 28 passes through and connects the outer limiting clamping mechanism 21 and the mounting base 27. Through rod 26 passes through each group of inner limiting clamping mechanisms 22, and the through rod 26 is connected to each group of inner turntables 227. Pressing block 213 is engaged with movable block 215 in motion, and pressing protrusion 226 is engaged with push block 224 in motion.

[0052] The implementation principle of a large-scale tubular column welding and forming system in this embodiment is as follows: During use, the tubular column to be welded is passed through the tubular column limiting mechanism 2. Hollow tubular columns pass through the tubular column limiting mechanism 2, and the column wall is clamped in the gap between the outer limiting clamping mechanism 21 and the inner limiting clamping mechanism 22. Figure 2 As shown, after the tubing passes through the tubing limiting mechanism 2, the operator rotates the handle 25. The handle 25 rotates and drives the connecting frame 24 to rotate. The connecting rods 23 connected to both ends of the connecting frame 24 are driven synchronously. At the same time, the through rod 26 connected to the inner side of the connecting frame 24 also rotates synchronously.

[0053] By deflecting the connecting rod 23, the connecting rod 23 synchronously drives the outer contour 211 connected to it to rotate. The outer contour 211 drives the inner contour 212 on its inner side to rotate synchronously through the meshing teeth. The inner contour 212 then drives the pressure block 213 connected to its inner side to deflect synchronously. As the pressure block 213 deflects, it then presses the movable block 215. The movable block 215 is then pressed down, and the outer clamping block 216 connected to the movable block 215 is then driven to press down synchronously. The outer clamping block 216 is then pushed out to fix and clamp the outer wall of the column.

[0054] Simultaneously, the through rod 26 connected to the inner side of the connecting frame 24 rotates synchronously, thereby driving the inner turntable 227 connected to it to rotate synchronously. The inner turntable 227 then drives the outer turntable 225 to rotate synchronously through meshing gears. The pressing protrusion 226 connected to the outer side of the outer turntable 225 is also driven synchronously. The pressing protrusion 226 then squeezes the push block 224, which is then pushed. The push block 224 then drives the inner clamping block 223 connected to it to be pushed synchronously. The inner clamping block 223 clamps the inner wall of the tube column. The tube column is fixed by the inner and outer clamping of the outer clamping block 216 and the inner clamping block 223. The clamping limit between the outer limit clamping mechanism 21 and the inner limit clamping mechanism 22 can clamp and limit tube columns of different diameters.

[0055] Example 2:

[0056] Combination Figure 7 The welding mechanism 3 proposed in this embodiment includes:

[0057] Support platform 31 supports the main body of welding mechanism 3; support frame 32 is fixedly connected to the top of support platform 31 at the bottom, and the top of support frame 32 supports column limiting mechanism 2, which is connected to the bottom of mounting base 27.

[0058] A movable rod 33 is connected to a support frame 32; a movable block 34 is sleeved on the outer surface of the movable rod 33; a movable platform 35 is connected to the movable block 34, and the movable block 34 moves on the outer surface of the movable rod 33.

[0059] The welding mechanism 3 also includes: a mounting plate 36, which is fixedly connected above the moving platform 35; a rotating shaft 37, which is located at the top of the mounting plate 36, and a welding shaft 38 is connected to the outside of the rotating shaft 37. The welding shaft 38 and the mounting plate 36 are movably connected through the rotating shaft 37. A receiving shaft 39 is connected to the outside of the welding shaft 38, and a ball head block 310 is engaged with the inside of the receiving shaft 39. A welding head 311 is connected to the outside of the ball head block 310.

[0060] Welding mechanism 3 also includes:

[0061] A drive motor 312 is mounted above the support platform 31. A motor shaft 313 is connected to the drive motor 312. A telescopic rod 314 is connected to the outside of the motor shaft 313. A receiving block 315 is connected to the top of the telescopic rod 314 and is connected to the bottom of the moving platform 35. A slot is opened on the receiving shaft 39, and a ball head block 310 is inserted into the slot in the receiving shaft 39. The ball head block 310 deflects in the slot on the receiving shaft 39 to adjust the angle. The pipe column limiting mechanism 2 is mounted above the welding mechanism 3, and the welding head 311 is located below the welding mechanism 3.

[0062] The implementation principle of a large-scale pipe column welding and forming system in this application embodiment is as follows: After the pipe column limiting mechanism 2 clamps and limits the pipe column, the welding mechanism 3 works. Through the operation of the drive motor 312, the drive motor 312 drives the telescopic rod 314 to move through the motor shaft 313, controlling the extension and retraction of the telescopic rod 314. The receiving block 315 connected to the top of the telescopic rod 314 moves synchronously, driving the moving platform 35 connected above it to move synchronously. The moving platform 35 then drives the moving block 34 to move synchronously on the moving rod 33, adjusting the position of the moving platform 35. The mounting plate 36 connected above the moving platform 35 keeps moving synchronously, thereby driving the welding head 311 to adjust its lateral position. The welding shaft 38 can be deflected on the mounting plate 36 by rotating the shaft center 37, adjusting the tilt angle of the welding shaft 38. The ball head block 310 can be deflected inside the receiving shaft 39, allowing for full-angle adjustment of the ball head block 310's angle position, thereby driving the welding head 311 to adjust its angle, thus realizing the welding of the clamped pipe column.

[0063] Working principle: During use, the pipe column to be welded is passed through the pipe column limiting mechanism 2. Hollow pipe columns pass through the pipe column limiting mechanism 2, and the pipe column wall is clamped in the gap between the outer limiting clamping mechanism 21 and the inner limiting clamping mechanism 22 (e.g., Figure 2 (As shown in the state), after the tubing passes through the tubing limit mechanism 2, the operator rotates the handle 25. The handle 25 rotates and drives the connecting frame 24 to rotate. The connecting rods 23 connected to both ends of the connecting frame 24 are driven synchronously. At the same time, the through rod 26 connected to the inner side of the connecting frame 24 keeps rotating synchronously.

[0064] By deflecting the connecting rod 23, the connecting rod 23 synchronously drives the outer contour 211 connected to it to rotate. The outer contour 211 drives the inner contour 212 on its inner side to rotate synchronously through the meshing teeth. The inner contour 212 then drives the pressure block 213 connected to its inner side to deflect synchronously. As the pressure block 213 deflects, it then presses the movable block 215. The movable block 215 is then pressed down, and the outer clamping block 216 connected to the movable block 215 is then driven to press down synchronously. The outer clamping block 216 is then pushed out to fix and clamp the outer wall of the column.

[0065] Simultaneously, the through rod 26 connected to the inner side of the connecting frame 24 rotates synchronously, thereby driving the inner turntable 227 connected to it to rotate synchronously. The inner turntable 227 then drives the outer turntable 225 to rotate synchronously through the meshing gears. The pressing protrusion 226 connected to the outer side of the outer turntable 225 is also driven synchronously. The pressing protrusion 226 then squeezes the push block 224, which is pushed. The push block 224 then drives the inner clamping block 223 connected to it to be pushed synchronously. The inner clamping block 223 clamps the inner wall of the tube column. The tube column is fixed by the inner and outer clamping of the outer clamping block 216 and the inner clamping block 223. The clamping limit between the outer limit clamping mechanism 21 and the inner limit clamping mechanism 22 can clamp and limit tube columns of different diameters.

[0066] After the tubing clamping mechanism 2 clamps and limits the tubing, the welding mechanism 3 operates. Driven by the motor 312, the motor shaft 313 drives the telescopic rod 314, controlling its extension and retraction. The receiving block 315 connected to the top of the telescopic rod 314 moves synchronously, causing the moving platform 35 connected above it to move synchronously. The moving platform 35 then drives the moving block 34 to move synchronously on the moving rod 33, adjusting the position of the moving platform 35. The mounting plate 36 connected above the moving platform 35 also moves synchronously, causing the welding head 311 to adjust its lateral position. The welding shaft 38 can deflect on the mounting plate 36 by rotating the shaft center 37, adjusting its tilt angle. The ball head block 310 can deflect inside the receiving shaft 39, allowing for full-angle adjustment of its position, thereby adjusting the angle of the welding head 311 and enabling welding of the clamped tubing.

[0067] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
